Water level

What this means

At 2.73 ft, the Long Tom River near Alvadore is below normal for mid-October.

The level is falling, down 0.43 ft over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. Over the past 30 days it has moved between 2.46 ft and 3.55 ft.

Fall is often low-water season on rivers, and it usually takes a few days of steady rain to change that. The sensor also reports a water temperature of 59 °F.

Compared with 5 years of daily readings for this time of year. How to read levels

What the stage means on the water

Low water means more dragging on shallow riffles and slower floats. Fish crowd into the deeper runs, and warm, low water stresses them, so play and release them quickly.
